btw, is there any news on this patch?  I'm quite keen on dumping
LilyPond's Rational class in favor of Scheme rationals, but adding gc
mark functions for that is just too much work; BGC would be a nice
soluiton to this.

Well, no real news.  My "not-so-meaningful benchmarks" (running a
loop[*]) reproductively show that "GBGC" is noticeably slower than "real
Guile" (1.5 to 2 times slower).

On larger samples the difference gets smaller.
With a 128mb footprint (GC tree benchmark), the difference is that BGC is just 23% slower,
